IMPROVEMENT IN DISINFECTING C OVERS FOR FAILS.

Specification forming part of Letters Patent No. 175,843, dated April 11, 1876; application filed September 21, 1875 resented in the accompanying drawings, of

which- Figure 1 is a top view, Fig. 2 a bottom view, and Fig. 3 a transverse'section, of one of the said covers.

The cover A is provided with a chamber, B, having openings'aa in its top. It also has a removable bottom, b, perforated with open.-

V ings c c, the bottom being held to the sides of the chamber by what is termed a bayonet connection. 7,

There is placed within the cover a cloth bag, 0, containing a quantity, D, of charcoal or some other proper disinfecting or deodorizin g matter or substance, the bag, with its filling,

being to enable the gases escaping from the vessel upon which the cover may be placed to pass into it through such cover.

When the cover is applied to any vessel containing offensive matter, the fumes or gas generated by the offensive matter are compelled to pass into or through the disinfecting or deodorizing substance or compound, and to become innocuous and inoffensive. When the charcoal or other disinfecting substance or compound has become saturated with gas, a new supply can be easily put into the receptacle by removing the loose sliding bottom or cover of the receptacle. The uses for this article are very numerous in sick-rooms, hospitals, dissecting-rooms, and in houses generally.

This cover is applicable, with great advantage, to numerous vessels, such as milk-cans, meat-boxes, refrigerators, fruit-cans, &c., it being for the purpose of'keeping the offensive or injurious gases in the atmosphere from coming in contact with their contents, when a supply of air may be necessary or desired to reach said contents.

I am aware that a dcodorizing-oomr consists of a covered pan provided with a nozzle for supplying it with liquid, and also with an opening in its bottom, and a valve to such opening, the said opening being to discharge such liquid into a vessel when covered by the pan, and the valves being to close the opening as occasion may require. Therefore I do not claim such, my disinfecting or deodorizing apparatus being of a difl'erent construction, and designed tohold charcoal, or a matter through which the gases arising from a vessel, when covered by such apparatus, may pass, and flow through the bottom and top of such apparatus.

I therefore claim- The improved manufacture or dcodorizing or disinfecting apparatus or cover described, consisting of the flanged, chambered, and perforated cover A, the removable and perforated bottom I), and the gas-pervious bag 0, of

charcoal or disinfecting or deodorizing matter, allconstructed and arranged substantially as specified.
